I thought insulated toilet tanks were pretty standard these days but I was at a Lowe's on the weekend and they had a Kohler Cimmarron complete toilet-in-a-box on sale. It was a good price but I was surprised that it came with an uninsulated tank. I saw the same thing with a Kohler Wellworth complete in-a-box at Home Depot a few weeks ago.

I was hesitant to buy it and have a sweating tank all the time. The sales guy at Lowe's said that because 1.6 gallon toilets fill with less water, it comes to room temp fairly quickly and sweating tanks aren't much of a problem. He said that's why manufacturers aren't always selling insulated tanks. Any thoughts on this? I'm drawing water at my cottage right from the lake and it can be pretty cold depending on the time of year.

I have never used an insulated tank; in fact, I have never seen one in a store in SoCA or here. However, if your inside humidity is a bit high, you may need one. Our climate here is dry and we run a humidifier all the time, summer and winter.

Thanks. I do have high humididity part of the year in our area so tank sweating could be a problem. That's why I figured that insulated tanks were pretty much standard around here now and the suggestion that low-flush toilets were not as prone to sweating was new. It makes sense in theory that a lesser water volume would warm to room temp quicker but I wondered what people were finding in real installations. We run a de-humidifier in our place during the summer so we're in the opposite situation to yours.

Thanks again everyone and I'd still like to hear if anyone has had sweating problems on a low flow toilet with an uninsulated tank.

I have a Wellworth in my house in the Catskills, which is a great low flow flusher, but it will occassionally sweat in the summer. For me, sweating is a result of a lot of people using the toilet and high ambient humidity. My incoming well water is around 45 degrees but will warm up to around 60 if there's low usage. But when the girls visit on a humid summer day, the tank can look like a glass of frosty iced tea.

Thanks Jigs. My place is located in central Ontario lake country so we're pretty similar to you in terms of place and climate. We get a lot of humid summer days too. I have since checked out some other Kohlers and none of them have insulated tanks. Since I've heard good things about the Kohlers I will probably buy one anyways - insulated or not.Thanks a lot for the input.
